Equilibrium Onions?
L. Ramos, D. Roux, P. D. Olmsted +1
We demonstrate the possibility of a stable equilibrium multi-lamellar (``onion'') phase in pure lamellar systems (no excess solvent) due to a sufficiently negative Gaussian curvatu…

Spatio-temporal dynamics of wormlike micelles under shear
L. Becu, S. Manneville, A. Colin
Velocity profiles in a wormlike micelle solution (CTAB in D2O) are recorded using ultrasound every 2 s after a step-like shear rate into the shear-banding regime. The stress relaxa…

A spatio-temporal study of rheo-oscillations in a sheared lamellar phase using ultrasound
Sebastien Manneville, Jean-Baptiste Salmon, Annie Colin
We present an experimental study of the flow dynamics of a lamellar phase sheared in the Couette geometry. High-frequency ultrasonic pulses at 36 MHz are used to measure time-resol…
